Answer:

Your problem isn't that toUpperCase() isn't working, it's that your code never gets to that point.

Your

if (al.charAt(al.indexOf(str.charAt(i))+1) == vo.charAt(vo.indexOf(str.charAt(i))))

never passes, because of that +1. There's no need for that there, and if you remove it, uppercase vowels will appear. There are other problems with your code beyond that point, but I'll let you solve them as part of the challenge :-)
